My daughter is 13 months old and eating solids and has been drinking milk for about a month now, and the last week or so she has been throwing up multiple times a day. Its a very watery throw up, almost like spit up, but smells like vomit. It doesn't seem to matter what she eats or drinks, it happens after each feeding. At first I thought maybe it was that she was lactose intolerant but after reading about that, I dont believe that is it. Anybody have any ideas what it could be?
